TSB12LV32: Avionics SEE rates for the 1394 interface

John:

    I will check if we have similar information for avionics environment.

Brian

Thank you.

The other device is the PHY, tsb41ba3a.

Also, do the devices contain Boron10?

Hi John:

   What special report needed for avionics environment? I don't think anyone in our team knowing this.

Regards

Brian

The Avionics FADEC page (Full authority digital engine control (FADEC) design resources | TI.com) states:

• Enhanced products (EP) and high-reliability components for long service life.

The avionics environment at 40Kft, 45 degrees has a typical high energy neutron flux of 7500 N/cm/hr compared to NYC rate of 13 N/cm/hr.  The high energy neutrons have energy levels in the range of 1 MeV to 20 Mev, as opposed the the 0.7 eV in the Reliability Estimator. Typically, the devices have a value either in  FITs at NYC or cross-sectional area which are scalable to the flux at  desired locations.

I found tsb41ba3a-ep.pdf and tsb12lv32-ep.pdf. Since these are EP, I expected they may have an enhanced reliability report for the Avionics environment.

I am a little surprised since TI has web pages addressing Avionics and Space. 

High energy neutrons can push soft failure rates up over 1 lambda.

Space applications make it difficult to send a field tech to power cycle a piece of equipment.
